Pirate Invasion

The Pirate Invasion is an event added in the 1.2 update. They behave similarly to the Goblin Army and Frost Legion, and are summoned by using a Pirate Map, dropped by any enemy killed in an Ocean Biome. When all of the enemies in this event are defeated, the Pirate NPC will move into an available house. A Pirate Invasion has a 1/15 chance to occur every day once the Wall of Flesh has been defeated and at least one Demon Altar or Crimson Altar has been destroyed. A warning message, "Pirates are approaching from the (East/West)!" will repeat a few times until "The Pirates have arrived!" displays and Pirates begin spawning. All of the event's enemies can be damaged by Lava. Combined with the sufficient rarity of their drops, Lava Farms had seen some light.

Note: The world must be in Hardmode in order to obtain the Map and the Pirate Invasion will only happen if the player has at least 200{{Hp}P}}. There are 6 event-exclusive enemies that appear during this event.

Notes

You cannot summon another pirate invasion if one is currently occuring even if a Pirate Map is used.

The player can use the Map, but nothing will happen, and the Map is not consumed.

Just like the Goblin Army, an in-game week must pass before another can occur.

The player must have at least 200 in order for the Pirate Invasion to happen, even when using a Pirate Map.

In mobile you can get the pirate map in any biome, as long as it is in the outer thirds of the world where King Slime can naturally spawn.

Prior to 1.3.0.1, the pirate invasion played the GolemTheme due to no invasion-specific themes existing at that time.

Try to stand in a small box with a platform floor, then use Yoyos like Hel-Fire, Amarok, or Chik with yoyo bag to deal very high damage to those pirates with least damage taken. This method is useful with early-hardmode players when the Pirate Invasion event occurs a few days after Wall of Flesh is defeated.
